flying with spring airlines to Shanghai Pudong (T2). then trip with China Airlines from T2.

I need to transfer flights (including picking up the luggage at arrival and checking-in again).
I wanted to know if the departure and arrival for those companies are far, how is the best way to go to transfer and how long do you think the whole transfer process is going to take?

My airline is proposing to change my flight with China airlines to a sooner time and I am worried that I might not have enough time between flights. Specially because Spring Airlines are known for their delays so I want to be sure to have plenty of time.

Thank you for your help.
Best,
Susana
